PackageBuilder builds a simple command-line structure by SwiftPM

Recently I created PackageBuilder to build a simple command-line structure easily by SwiftPM. It’s very simple, but it saves a lot your development time if you’d like to create a command line tool like Marathon created by @JohnSundell. This automatic tool is based on his great article. Also, This tool inspired by JohnSundell/SwiftPlate. If you agree with them, I’m sure you’ll like it:)
